The term mucocele was first coined by Rollet in 1896. Onodi first described the histology of a Mucocele in 1901. Mucoceles are mucous filled epithelium lined sacs that typically fill a paranasal sinus. Macroscopically, mucoceles are thick walled grayish cysts which are histologically characterised by a pseudostratified columnar epithelial cells with few ciliated cells, hypertrophic goblet cells, fibrous thickening of submucosa and sterile mucus with cholesterol crystals.
